Abstract
The present invention relates to a kind of Wear Characteristics of Epoxy Adhesive agent prescription, specifically a kind of formula for pouring into a mould polyether-type PU rubber and metal adhesive primer.The formula of the present invention includes：618 epoxy resin 100；Imidazole curing agent 3 ~ 5；Polysulfide rubber 5 ~ 40；Performed polymer 5 ~ 40；Solvent 30 ~ 100.It is an advantage of the invention that while adhesive property requirement is met, the effect that preparation is simple can be reached.It after the completion of cast polyether-type PU rubber prepared by the present invention is applied with metal adhesive primer in metal surface, can be deposited in normal room temperature environment the long period, then carry out follow-up cast polyurethane technique, it is small to application environmental requirement, few using limitation.
Description
Technical field
It is specifically a kind of cast polyether-type PU rubber and metal adhesive primer the present invention relates to a kind of Wear Characteristics of Epoxy Adhesive agent prescription
Formula.
Background technology
EU is that PU rubber is one of more extensive elastomer of domestic application, and it not only has higher strong
Degree, elasticity and bearing capacity under hardness is waited, also with good oil resistant, sea water resistance, resistance to low temperature etc..Generally use at present
Casting is molded, applied in the entrant sound sealing of underwater acoustic transducer.PU rubber and metal are the great dissimilar materials of difference, and its is straight
Connect and bonded with casting of metals, adhesion is low, many methods using bonding hot vulcanization are carried out at a series of surfaces to metal first
Reason, then applies primer, finally carries out polyurethane vulcanization perfusion.At present, PU rubber and metal adhesive are often that lek is received with primer
The serial adhesive of glue, Chemlok adhesive, Thixon adhesive, Cilbond.But these adhesive weatherabilities are poor, are coated
Finish, it is necessary to be placed in the environment of clean dried, and PU vulcanizations of rubber perfusion must be completed in the short time, completion was entirely bonded
Journey.In addition, leakerna glue and the bonding force of brass and stainless steel be not high, the failure mechanics of test specimen are substantially metal smooth surface；
Chemlok and Thixon adhesive is for PU rubber from application that different metal is bonded, it is necessary to from different models.It can send out
Existing, the primer that existing bonding hot vulcanization mode is used is higher to application environmental requirement, and more using restriction ratio, technique will
Ask comparatively laborious.
The content of the invention
The technical problem to be solved in the present invention is to provide it is a kind of it is small to application environmental requirement, use the few cast polyethers of limitation
The formula of type PU rubber and metal adhesive primer.
In order to solve the above-mentioned technical problem, formula of the invention includes：618 epoxy resin 100；Imidazole curing agent 3 ~ 5；
Polysulfide rubber（5~40；Performed polymer 5 ~ 40；Solvent 30 ~ 100.
It is preferred that, the molecular weight of polysulfide rubber is in 1000-3000 g/mol in formula
It is preferred that, the imidazole curing agent in formula is 2-methylimidazole, the methylimidazole of 2- ethyls -4,2- ethyl imidazol(e)s, 2- benzene
One or more in base imidazoles.
It is preferred that, the solvent in formula is the one or more in toluene, dimethylbenzene, N, N- diformamides.
It is an advantage of the invention that while adhesive property requirement is met, can Star to preparation is simple
Effect.After the completion of cast polyether-type PU rubber prepared by the present invention is applied with metal adhesive primer in metal surface, Ke Yi
Deposited in normal room temperature environment the long period, then carry out follow-up cast polyurethane technique, environmental requirement is small, use limit to applying
System is few.
Embodiment
Embodiment cited by the present invention, is only intended to help and understands the present invention, should not be construed as to present invention protection model
The restriction enclosed, for those skilled in the art, without departing from the inventive concept of the premise, can also be right
The present invention is made improvements and modifications, and these are improved and modification is also fallen into the range of the claims in the present invention protection.
The formula of the present invention includes：618 epoxy resin 100；Imidazole curing agent 3 ~ 5；Polysulfide rubber（Molecular weight 1000 ~
3000 g/mol）5~40；Performed polymer 5 ~ 40；Solvent 30 ~ 100.
It is preferred that, the imidazole curing agent in the formula is 2-methylimidazole, the methylimidazole of 2- ethyls -4,2- ethyl miaows
One or more in azoles, 2- phenylimidazoles.
It is preferred that, the solvent in the formula is the one or more in toluene, dimethylbenzene, N, N- diformamides.
The formula of note polyether-type PU rubber and metal adhesive primer disclosed by the invention is meeting the same of adhesive property requirement
When, the existing effect that preparation is simple can be reached.Cast polyether-type PU rubber and metal adhesive bottom prepared by the present invention
After the completion of glue is applied in metal surface, it can be deposited in normal room temperature environment the long period, then carry out follow-up polyurethane and poured
Note technique is small to application environmental requirement, few using limitation.
